Industrial process control process is studied, because of the impact of the control environment and control param-eters of nonlinear interference effects, leading to control dead zone, appear unstable control problem occurred. The process of traditional methods using PID variable structure control algorithm for industrial process control, the control performance of environment interference of large dead time control effect, it has large amplitude. A control method of PLC and fuzzy dis-turbance process protection dead zone is proposed based on improved method, based on PLC logic control chip, design of industrial process control system hardware design, control of sliding surface, constructing differential control equation of nonlinear interference environment and control parameters, using the normal status related feature extraction method, PLC programmable logic fuzzy disturbance control based on the perturbation, achieve the process of log compensation anti dead improved control algorithm. The simulation results show that, by using this control system, with a larger linear control inter-val, reduce the process disturbance and dead time range, can improve the stability and the robustness of the industrial pro-cess.
